serviceTask處理：

 

@Component
public class SwTimeOutProcessorListener implements JavaDelegate {

    @Autowired
    private TimeOutManagerService timeOutManagerService;
    @Autowired
    private TaskService taskService;

    @Override
    public void execute(DelegateExecution execution) throws Exception {
        //獲得事務id
        String businessKey = execution.getProcessBusinessKey();
        Task task = taskService.createTaskQuery().processInstanceId(execution.getProcessInstanceId()).singleResult();
        String assignee =task.getAssignee();

        System.out.println(assignee);

        //插入超時記錄
        //timeOutManagerService.addTimeOut(Integer.valueOf(assignee), Integer.valueOf(businessKey));


    }

}

 

 

定時邊間事件：cancelActivity 說明：

cancelActivity屬性：true時，當timer觸發時，當前的activity被中斷（流程結束）;

                                false時，當timer觸發時，不會被中斷（流程原點，流程不會結束），

 

當執行循環定時器時，雖然cancelActivity=true，但是該acitivity還是會持續生成

 

cancelActivity默認爲true中斷事件(結束流程)

cancelActivity爲false非中斷事件(還停留在原地，流程不結束)

中斷和非中斷的事件還是有區別的。默認是中斷事件。

非中斷事件的情況，不會中斷原始環節，那個環節還停留在原地。 對應的，會創建一個新分支，並沿着事件的流向繼續執行。
